Software accounted for $274 million in retail SKUs for software throughout May, and Hardware sales garnered $187 million. Both hardware and software are up compared to 2013's figures.

According to DualShockers Sony was quick to release a press note about being number one yet again when it comes to hardware sales, with the senior vice president of PlayStation brand marketing, Guy Longworth, saying...

“PlayStation continues to be the best place to play for innovative IP, as PS4 was the preferred platform for May’s biggest releases, including Watch Dogs and Wolfenstein: The New Order, and held four of the top five spots for next gen software sales. PS4 is the leading next-gen platform for sports, highlighted in May by the best-selling sports game, MLB 14: The Show.”

While Sony released no updated sales figures about the PlayStation 4, it was recently revealed by Statista [via Wall Street Journal] that the PS4 has breached the 8 million install base mark, appropriately sitting at 8.1 million units sold-through to customers.

Meanwhile, Nintendo responded in kind to the monthly figures – opting not to share specific numbers, just the same as Sony – with Gamespot reporting that the Big 'N' revealed that...

“Wii U sales are up over 85% over April and over 90% over May of last year.”

If you look at the breakdown, the Wii U only sold 60,000 SKUs in North America over the course of those three months, which means that the Wii U could have only sold an estimated 20,000 in the month of May in North America (give or take). Based on the information that Nintendo provided Gamespot, that would mean that this May the Wii U could have sold 38,000 units in North America alone. That's not too bad considering that Mario Kart 8 launched at the very end of the month and would only have accounted for a very miniscule effect on the total sales for the month.

Earlier today Nintendo of America president Reggie Fils-Aime had revealed that the since the release of Mario Kart 8 the Wii U was moving around four times the amount of units two weeks prior to the release of the flagship racing title.

38,000 is neither good nor bad, but it all boils down to what the system moves in June. Having Reggie confirm that the system is still maintaining momentum moving into (and presumably out of) E3 is a good omen.

Interestingly enough, Microsoft has been silent (so far) about their numbers; and if the Xbox One managed to perform on par or less than the Wii U then that could be a huge blow to the brand. We'll provide an update if (or when) Microsoft decides to issue a response.
